SWIMMING MACHINE Application filed July 29;.

This invention relates to swimming machines, andits general object is to provide a swimming machine that is made up of de tachably associated parts, that can be. assembled and disassembled in an easy and expeditious manner, and by employing detachable parts, the machine can be conveniently carried when disassembled and, stored in minimum space. v

Another object of the invention is to provide a swimming machine that can be-m'anually propelled through the water at a great speed and is not only comfortable to ride upon but iseasily manipulated. v

A still further object of the invention is to provide a swimming machine that is simple in construction,inexpensive to manufacture and is extremely eflicient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement ,of the several parts, to behereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. i p

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of a machine constructed in accordance with one form of the present invention- Figure 2 is a top plan view thereof Figure 3 is a front view.

Figure 4 is a sectional view taken approximately on line 4-4 of Figure 1,. looking in the direction of the arrows- V F ignre 5 is a side elevation of a modified form of' the present invention.

Figure 6 is a top plan view of the form as shown in Figure 5.

Figure 7 is afront view of the modified form.

Figure 8 is a sectionalview taken approximately on line 88 of Figure 6.

Referring to the drawings in detail, the reference numeral 1 indicates the body of the form of the machine as shown in Fig- 1932. Serial No. 626,006.

ures 1 to 4 inclusive and this body includes what may be termed a horizontal portion 2 and an inclined portion 8. The major portion of the body is substantially T-shape in. cross section as will be noted upon inspection of Figure 4, in order to provide a flange which depends from the top of the body and extends longitudinally thereof. Formed with the flange and depending therefrom is a keel 4 having secured to its rear end a bracket 5 which is provided with a bearing for rotatably receiving the rear end of the drive shaft 6. v

The forward end of the body has secured thereto a hanger 7 that is provided with an opening in its outer end, and the opening. receives a bearing. to accommodate a stub shaft 8 which has secured to its ends crank handles 9. The stub shaft 8 has also fixed thereto a bevel-gear 10 which meshes with a pinion 11 the latter being secured to the forward end of the drive shaft 6, whereby upon rotation of the bevel gear 10 through the instrumentality of the crank handles ,9,

the drive shaft will be rotated for driving.

the propeller 12. The crank handles have pedals 13 which are secured to the outer ends thereof, and these pedals are rotatably mounted, as well as being substantially oval shape in cross section to provide a convenient hand grip for the user of the device.

Secured to the flange of the body 1 and disposed adjacent the ends of the horizon tal portion thereof are brackets 14 which extend above the body and terminate at their upper ends in sleeves for the purpose of receiving curved tube members 15 that are secured in the sleeves through the instrumentality of set screwsv 16. The tube members are designed to accommodate the body of. the user and are curved for that purpose.

The upper ends of the tube members have secured thereto substantially U-shape members 17, and each of the U-shape members have formed with the outer ends thereof slotted ears 18 for the purpose of receiving bolts 19 that are fixed to one of the ends of straps 20, while the opposite ends of these straps are secured to the U-shape members as best shown in Figure 4.

by set screws 33. p x Detachably associated or otherwise se cured to the outer endsof the curved tube members 22 are secured strips 25 that carry a shaft 26 mounted for rotation therein.

The shaft 26 is vertically disposed and has secured to its opposite ends rudders 27 which extend upon opposite sides of the cross rod L member 24 as best shown in Figure 1. The str1ps 25 are secured to the rod members 22 by set screws 28. l V In the form of the invention as disclosed in Figures 5 to 8 inclusive, it will be noted that I employ a body 29 that is like.wise sub stantially T-ohape in cross section and this;

body includeshorizontal portions and an intermediate inclined portion. 7 e

Secured to the depending flange of the T-shape in cross section body are spaced brackets 30 having formed therewith sleeves 31' which have )assing therethrough curved tube members 32 that are fixed 1n the sleeves members 32 are clamping brackets 34; which include cooperating clamping plates held associated by set screws 35 andthese clamping bracketshave secured thereto rodfmem bers 86 arranged in parallelism as best shown in Figure 8. The rod members 86:

have secured to the ends thereof V shape brackets 37, and the outer endsof "theQV shape brackets have bearings formed therewlth to accommodate stub shafts 38 that are,

secured to the ends of the pontoons 39 whereby the ,pontoons are, mounted for rotation as will'be apparent.- Formedwith the pontoons and'spirally arranged thereon are propelling fins40.

' The pontoons have secured to the forward ends sprockets 41 which have trained thereabout sprocket chains 42 that are also trained about sprockets 43 secured to a shaft I 44- and this shaft has also secured thereto a pinion 4-5. Journaled in the forward horizontal portion of the body 29 is a crank shaft 46 that has fixed thereto a bevel gear 47 and this bevel gear meshes with the pinion 45. The crank shaft has mounted for rotation on its ends pedals l8 whereby upon rotating the crank shaft through themedium of the pedals the shaft 44 will be rotated for rotating the pontoonsthrough the instrumentality of the sprocket chains and their sprockets for propelling the machine through the water.

The brackets 30 are provided with openings which have secured therein a rod frame 49 that is elongated in formation and extends rearwardly as will be noted uponinspection ofFigure 6, and secured to the rod frame 49v are clamping strips which carry rudders 50.

a From the above description and disclosure of the drawings, will be obvious that I have provided a swimming machine that includes detachably associated parts that can be assembled and disassembled in an ex peditious manner and with very little effort.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may makechanges in the construction andin the combination and arrangement of the several parts, prov1ded that such changes fall withinthescope of the appended'claim.

WhatI claim is:

A swimming machine comprising a body having an inclined forward portion and a horizontal rearward portion, propelling means for said machine and having connection with the respective portions of said body for disposal. at an inclination, a depending "flange included in said body,

brackets secured tothe flange and provided with openlngs, curved tube members secured to the brackets, pontoons detachably secured tions of the shaftfor disposal above and below the rod members;
